15.9x8 Hard tyre

Hard front tyre 15.9x8 from Sideways: control and consistency at the front axle

The hard tyre 15.9x8 from Sideways (reference SWFT01) is designed for the front axle of 1/32 scale slot cars. Its hard compound —known as No Friction by the brand— reduces rolling resistance at the front, contributing to cleaner steering and a more predictable response when exiting corners.

Main features

• Size: 15.9 x 8 mm
• Rim compatibility: 15.8 to 17.3 mm in diameter
• Hard compound (No Friction): minimises friction at the front axle
• Official Sideways reference: SWFT01

Function and performance

On the front axle of a slot car, the choice of compound directly influences how the car follows the racing line. A hard tyre like this offers less deformation under lateral load, resulting in more stable guiding and more consistent behaviour throughout the session, especially on fast tracks or in club competitions where consistency lap after lap makes the difference.

The compatibility range with rims from 15.8 to 17.3 mm makes it suitable for various front wheel configurations, providing some versatility within the Sideways preparation catalogue.

Compatibility and mounting

Always check the outer diameter of your rim before mounting. The tyre should fit snugly without lateral play; if necessary, fine and uniform sanding on a flat surface ensures perfect centring once installed. For rims at the upper limit of the range (close to 17.3 mm), a more careful adjustment may be required.

Ideal for…

Enthusiasts and competitors preparing Sideways cars or any compatible chassis who want to reduce resistance at the front end without sacrificing steering stability. It is also interesting for those experimenting with different front/rear compound combinations in search of optimal balance.

Frequently asked questions

What does "No Friction" mean in Sideways tyres?

It is the term used by Sideways for its hard compound tyres intended for the front axle. The aim is to reduce friction in that position, where excessive grip can negatively affect steering and the overall balance of the car.

How do I know if this tyre is compatible with my front rim?

Measure the outer diameter of your front rim. If it is between 15.8 and 17.3 mm, the SWFT01 is compatible. If in doubt, consult the specifications from your rim manufacturer or compare it physically before gluing.

Is it mounted with glue?

Yes, like most slot tyres, it is recommended to secure the tyre to the rim with a small amount of cyanoacrylate, ensuring it is well centred. After gluing, it is advisable to true the tyre if the appropriate tool is available to ensure concentricity.

Is this tyre also suitable for the rear axle?

It is specifically designed for the front axle. For the rear axle, Sideways offers references with different compounds, generally softer or with grip, which are suitable for traction.

The Sideways SWFT01 is a hard compound front tyre measuring 15.9x8 mm, compatible with rims ranging from 15.8 to 17.3 mm. Designed as a No Friction front tyre for 1/32 slot car racing, it delivers consistent steering response and reduced rolling resistance at the front axle — a reliable choice for club racing and serious slot car preparation.
